PRESSURE-RELEASE FOR CLOTHES-WJRTNGJEES."

To all whom it may concern Be it known that T, ALBERT E. HoLADAY, a citizen of the United States, residing at Naugatuck, in thecounty of New Haven and State of Connecticut, have invented certaln new and useful Improvements in Pressure- ]Releases for Clothes-Wringers, of which the following is a' specification, reference being had therein to the. accompanying drawing.

This invention relates to certain new and useful improvements in clothes wringers, and more particularly to a pressure release for the same, the object being to provide a clothes wringer with an invisible'p'ressure release so constructed that the same will be antomatically operated by the .abnormal separation of the rolls, means being provided for manually operating the same in case of the a failure of the automatic means working.

Another object of my invention is to provide a release which is exceedingly simple and cheap in construction and one which can/ be readily applied to the various forms of wringers now in use, the releasing members being mounted within the coil pressure springs in such a manner that they are raised vertically on the abnormalseparation of the rolls and brought into engagement with pivoted latches carried by the top bar so as to move the latches out of engagement with the keepers carried by the frame of the wringer in order to release the pressure.

Another and further object of the inven tion is to provide a novel form of manually operated means for operating the latches through the medium of a push button mounted in the top bar.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims. 3

showing the'manner' of mounting the same in the angled plate carried by the top bar,

Fig. 5 is a detail section showing a slightly modified form of bearing and releasingbar. Like numerals of reference refer to like parts in the several figures of the drawing.

Tn carrying out my invention I employ a wringer frame 1 having slotted side bars 2 in which are mounted pressure roll carrying shafts 3 and 4, provided with the usual pressure rolls 5 and 6, said rolls carrying meshing gears, not shown, inclosed by gear casings 7. The lower pressure roll carrying shaft 3 is mounted in fixed bearings 8 and mounted on the upper pressure roll carrying shaft 4: are bearings 9 carrying pressure springs 10 which are engaged by hearing plates '11 carried by the ends of the pressure bar 12, said bearing plates being provided with apertured lugs 13 extending down into the convolutions of the pressure springs 10 as clearly shown in Figs. 1 and 3. I

Secured across the slots of the side'bars2 at their upper ends are keepers 14 in the form of plates-having openings 15, the lower edges of which are beveled as shown at 16 for the purpose hereinafter fully described.

Arranged within the slotted side bars between the keepers is a movably mounted top bar 17 which is provided with recesses 18 at its. ends over which are arranged angled plates 19 provided with spaced apertured ears 20 in which are mounted latches 21 upon pivots 22 extending through the apertures of the ears 20 as clearly shown in Fig. 4, said latches being provided with tail portions 23 having positioning pins 24 over which are arranged coil sprin s 25 which are held in position on the ang ed plates by positioning pins so as to normally-hold the pivoted latches in extended'position under the lower edges of the keepers 15 in order to hold the top bar is predetermined position.

The top baris provided with pressure screws 25 which engage the bearing plates 11 of'the pressure bar 12 so as to adjust the pressure on the pressure rolls 5 and 6 in the ordinary manner. I

In order to provide means for manually operating the pivoted latches 21 I provide the top bar with a centrally disposed vertical bore 26 which communicates with the longitudinal slots 27 formed in the under side of the top bar as clearly shown in Fig.

at Fig. 4 is a detail view of one of the latches 1. Pivotally mounted within the slots 27 are Patented Nov. 5, rare. Application filed January is, 1917. Serial No. 142,090.

levers 28 which are provided with angled ends 29 adapted to engage the beveled faces of lugs 30 formed on the tail portions 23 of the latches 22 so as to rock said latches on their pivots in order to move the latches out of engagement with the keepers which allows the top bar to move vertically within the frame, and as the latches move upwardly they ride into the openings 15 of the keepers so as to prevent the top bar from jumping out of the frame. Slidably mounted within the bore 26 is a push button 31 which is provided with a cross pin 32 at its lower end on which the inner ends of the levers 22 are mounted, said push button having a slot 33 through which passes a pin3 l for holding the push button in position within the top bar, and it will; be seen that when the push buttonis forced downwardly the levers are rocked on their pivots so as to oscillate the pivoted latches in order to release the top bar.

In connection with the manually operated means for operating the pivoted latches 22 I provide automatic means comprising releasing bars 35 arranged within the coil pressure springs 10,- the lower ends of said bars extending through the apertured bosses 9 of the bearing 9 and rest upon the upper pressure roll carrying shaft 4 as clearly shown in Fig. 1. The upper end portions of the releasing bars 35 extend through the apertured bosses 13 of the bearing plates 11, and are provided with internally threaded bores in which are adjustably mounted trip members 36 herein shown in the form of screws which can be rotated so as to adjust the relative position of theheads thereof in respect to the latches. As the pressure rolls 5 and 6 are separated abnormally the releasing bars 35 are moved upwardly so as to throw the trip members 36 into engagement with the tail portions of the latches which rocks the latches so as to move the latches out of engagement with the keepers and allows the top bar to move a predetermined distance upwardly within the frame to release the pressure rolls.

In the modification shown in Fig. 5 I provide a bearing 37 with a socket 38 in which the lower end of a releasing bar 39 is secured by a pin 40 so as ,to connectthe releasing rod to the bearing in order to prevent the same from turning to facilitate the adjusting of the trip members and to prevent the wearing of the releasing rod, or the danger of the same jumping out of the hearing when the pressure is released.

In the operation of a clothes wringer as I herein shown and described assuming that the parts are in the position as shown in Fig. 1 when a thick bunch of clothes or an operators hand is drawn between the pressure rolls so as to separate the rolls abnormally, the releasing bars are moved upwardly so as to throw the trip members into engagement with the latches which moves the latches out of engagement with the keepers and the top bar moves vertically within the frame until the latches ride into the openings of the keepers which prevents the top bar from jumping out of the frame.

In case'of the automatic means failing to work so as to release the pressure on the pressure rolls, the push button can be struck by the operator so as to throw the levers into engagement with the latches which moves the latches out of engagement with the keepers and allows the top bar to move vertically to release the pressure. After the pressure has been released and it is desired to reset the device, the pressure screws are adjusted so as to move the screws upwardly and by striking the top bar the latches ride on the inclined edges of the openings of the keepers back into position under the lower edges thereof to enable the pressure screws to be again adjusted so as to obtain the desired pressure on the pressure rolls.

From the foregoing description it will be seen that I have provided a pressure release for a clothes wringer in which a pair of pivotally mounted latches are mounted within the top bar in such position that they can be engaged by automatically operated releasing members or manually operated releasing members so as to move the latches out of engagement with the keepers carried by the frame to release the top bar.

While I have shown and described the releasing bars arranged within sockets formed in the upper bearings in a particular manner, I do not wish to limit myself to any particular manner of mounting these releasing bars in the bearings as any suitable means can 'be employed for mounting the rods in the bearings Without departing from the spirit of my invention.
